Preparation and Research on Anticorrosion Zinc-Rich Coating of Hydraulic Metal Structure

Abstract:

The types and addition dose of zinc in the zinc-rich coating have a significant impact on the character of coating. Two types of the zinc powders and the amount of zinc were researched in this paper. It reveals that flaky zinc coating is better than the spherical zinc coating on corrosion performance, and the performance of the coating will be the best only when the solid content of zinc is reasonable. The results also show that optimal solid content of flaky zinc are 62.5%, 60% and 60.5% in the inorganic zinc-rich coating, epoxy zinc-rich coating and vinyl resin zinc-rich coating, respectively.
